Question
stm32mp25: "EQOS_DMA_MODE_SWR stuck FAILED: -110" ethernet error in u-boot
Hello,
I am using the STM32MP257x-EV1 board with version 2022.10 of u-boot-stm32mp (with patch 0001-v2022.10-stm32mp25-beta.patch from commit dc5d7824 made on April 12, 2024).
When compiling u-boot + stm32mp257f-ev1.dts, only the eth2 interface is functional, the other interface displays the following error:
EQOS_DMA_MODE_SWR: mode: 00000000482c1000 - wait: 50
EQOS_DMA_MODE_SWR stuck FAILED: -110
After compiling u-boot-stm32mp, I used the dtc tool with u-boot.dtb to get my full dts file used and here is the configuration of eth1 and eth2.

Can anyone help me to solve this error ?
Thank you
